SKATE.

Application filed January 26, 1910.

To all whom it may concern:

Be it known that I, DANIEL M. PFAUTZ,

a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Skates, of which the following is a specification. A

My invention relates to improvements in.

skates, and more particularly to skates employing large wheels, which enable a high rate of speed to be attained with little effort, the object of the invention being to provide a skate of this character, in which the foot is supported close to the ground upon a platform, and the latter supported by comparatively large wheels at the sides of the platform, having an improved arrangement of roller bearings, which insure easy turning wheels, and take up side thrust during the operation of skating.

A further object is to provide an improved construction of side frames supported on the wheels, and providing a shield to prevent the wheels from throwing dirt upward upon the clothing of the skater.

A further object is to provide an improved arrangement of brake wheels, which enable the skater to check the speed and stop when desired.

A further object is to provide improved means for clamping the foot upon the foot supporting platform.

With these and other objects in view, the invention consists in certain novel features of construction, and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure l, is a view in longitudinal section through one of the side frames illustrating my improvements. Fig. 2, is a view in horizontal section. Fig. 3, is a rear end view, and Fig. 4, is a View in vertical cross section.

1 represents the foot supporting platform, which is secured to and supported by my improved side frames 2-2, which latter are provided with perforated ears 3, through which screws 4 are passed, and screwed into the platform 1. These frames 2 are preferably open work castings, comprising parallel side plates 55, which latter are made with circular disk like portions 6-6 between which the hubs 7 of wheels 8 are mounted.

Specification of Letters Patent.

Patented Dec. 2'7, 1910.

Serial No. 540,193.

There are four of these wheels 8 to each skate, and they are preferably provided with rubber tires 9 and are of any desired diameter, but preferably, appreciably larger than the wheels or rollers of ordinary skates. These wheels 8 are secured to turn with journals 10 around which latter at both sides of the wheels, roller bearings 11 are provided and turn in cups 12 in the frame, said cups being secured in position by means of plates 13 secured by screws 14, the outer plates 13 being preferably provided with beveled edges, so as to prevent any angles which might enable or permit one skate to catch against another. To take up the side thrust on the wheels 8, the wheels and the disk like portions 6 are provided with circular runways 15 to receive a circular series of balls 16, which balls take up the side thrust, and insure an easy running skate, and one that will be strong to withstand the rough usage to which such a device is apt to be put.

The parallel plates 55 of the frames 22, are connected by a shield or cover 17, which latter is preferably integral with the side plates, and is of the general curved form shown, and extends from a point about midway the height of the frame at the rear, to a point about midway the height of the frame at the front, and all across the top of the frames, so as to catch any dirt and moisture the wheels may throw upwardly, and protect the clothing of the skater.

In the extreme rear and lower ends of the frames 2 2, small brake wheels 18 are mounted to turn hard thereon. These brake wheels 18 are preferably rubber tired, and normally disposed above the ground, but when the skater desires to stop, it is merely necessary to tilt the skate backward upon the rear wheels to bring the brake wheels 18 into contact with the ground, and as these wheels turn hard upon their journals 19, they will effectually retard the speed of the skater and enable him to come to a stop.

The foot supporting platform is provided at front and rear with depending flanges 20 and with lugs 21, which support a rod 22 extending throughout the length of the skate, and having secured at its rear end a wing nut 23 to turn the rod. This rod is also passed through a depending lug 24 about the center of the platform, and is provided adjacent its ends with oppositely disposed screw threads 25, and the platform above these screw threaded portions of the rod is made with slots 26, through which ears 27 depend from the toe and heel clamps 28 and 29 respectively. These ears are provided with screw threaded openings to register with the screw threads of the rod, so that when the rod is turned by the winged nut 23, the heel and toe clamps will be adjusted toward or away from each other, so as to clamp or release the skaters foot, and by this construction it will be noted that the skate is constructed to fit any size shoe.

The toe clamp is preferably in the form of a casing to engage over the toe of the shoe, and when tightly clamped against the toe and the heel clamp against the heel, and further secured by means of a strap 30 secured at its ends to brackets 31 on platform 1, the skate will be rigidly secured over the shoe. This strap 30 is preferably provided with a buckle 32 to facilitate its adjustment to clamp around the instep of the skater.

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not restrict myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1. In a skate, the combination with a foot support, of side frames at both sides of the foot support, and to the lower ends of which said foot support is secured, said frames I said cups.

3. In a skate, the combination with a foot supporting platform, of side frames secured to the platform, a pair of Wheels located in each frame one behind the other, journals in said wheels supported in the frames, cups in said frames around the journals, and roller bearings around the journals in the cups, and plates secured to said frames and holding the cups in the frames.

4. In a skate, the combination with a foot supporting platform, side frames secured to the platform, a pair of wheels in each side frame located one behind the other, journals in said wheels supported in the frames, registering ball run-ways in the frames, and wheels and balls in said run-ways to withstand the side thrust on the wheels.

In testimony whereof I have signed my name to this specification in the-presence of two subscribing Witnesses.

DANIEL M. PFAUTZ.
